Hi Yoav, just for clarification: That was me. When they started talking about about PQC a decade ago, they mentioned algorithms like McEliece with public keys around 1MB. Not that this is a deal-killer. If necessary, we would come up with an IKE extension to have “jumbo-sized payloa

Hi, Scott. That was me. When they started talking about about PQC a decade ago, they mentioned algorithms like McEliece with public keys around 1MB. Not that this is a deal-killer. If necessary, we would come up with an IKE extension to have “jumbo-sized payloads” that had 24-bit lengths. IKE o

During the WG meeting in London, somebody (I forget who) asked me whether KE payloads larger than 64k. I thought I ought to clarify matters (as they are more complex than the brief answer I gave indicated). Of the proposed postquantum key exchange (and public key encryption algorithms, which c
